Save Thousands by Including Your PLC in Your Injection Pump Drive System

 

Two of the critical pieces of equipment for controlling injection pumps are the variable frequency drive and the PLC.

  • VFD – controls the pump motor
  • PLC – controls the logic, which defines what is happening at what rate and when

These two components must inter-communicate and operate together as a system. If they are not already connected before they arrive on site, installation and configuration is required for each device and between them.

Integrated Injection Pump Drive System

In an integrated system, the PLC and VFD come pre-configured and pre-integrated. While this system may cost slightly more than a traditional drive, it eliminates the need for a separate PLC and its integration. Eliminating the separate PLC saves $1,500 to $10,000 for the equipment, another $1,000 in integration and typical startup configuration costs of $2,000.

Rising to the Challenge
of Saltwater Disposal Management

Saltwater has long been a byproduct of oilfield production. With the dramatic increase in unconventional plays, water management has become a significant element in oilfield economics. Fracking jobs in unconventional plays routinely put ten times as much fluid downhole as were used in conventional plays. As much as 250,000 barrels of fluid is used during completion for each well.

Simple or Not Simple: Injection Pump Controls

Simple is almost always better. It certainly is when it comes to injection pump control. Using a fully integrated drive system reduces total cost, speeds on-site installation and improves reliability.

The key components of an injection pump system are:

  • Pump
  • Field signals
  • Drive
  • Controller
  • SCADA communications

There are several ways to simplify installation, operation maintenance and total cost.
